Given following query -

SELECT name, age FROM students WHERE age > 22

The result is -

name    age
----   ---
Kshitiz 23
Steve   22
Paul    24

How can I number the results sequentially? Like so -

serial  name    age
------  ----    ---
   1    Kshitiz 23
   2    Steve   22
   3    Paul    24

Please note that using surrogate key is not a solution. Because the surrogate id for record Kshitiz might be 9. I want whatever results are returned from whatever location to be numbered sequentially.

SELECT @a := @a + 1 serial, name, age
FROM students, (SELECT @a :=0) AS dummy
WHERE age > 22;

This works for MySQL. I was modifying from this example.

    You should have an ORDER BY something, otherwise it's a more or less random ordering. – ypercubeᵀᴹ Dec 27 '12 at 12:42
